PAPER FEEpljflG MECHANlSM FOR TYPE-WRITERS.

Nb. saaeso.

To all whom, it may concern:

Be it known that I JOHN MAYNARD, a citizen of the United States, residing atCleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful "Improvement in Paper-Feeding -Meehanisnr backward or forward any required distance without so changing the relations between the roll and the mechanism provided. for imparting the feed movements thereto that when the roll is next moved by said mechanism it will be moved either less or more than the regular feed distance.

The invention consists in the very simple construction and combination of parts shown in the drawings and hereinafter described and claimed. Y

In the drawings, Figure 1 is a rear elevation, and Fi 2 is a plan view, or a typewriter feed-r0 l embodying the invention and the parts of a typewriter immediately associated therewith. Fig. 3 is a vertical longitudinal section of said roll and operating mechanism, Fi 4 is anend view of the same from the left side of Figs. 1 and 2. Fig. 5 is a transverse sectional view of the feedroll. Fig. 6 is a sectional view in the plane indicated by line 6 6 of Fig. 3, showing the feed-roll-operating mechanism; and Fig. 7 is a View, partly broken away, of a modified construction of the invention.

Referring to the parts by letters, A represents, the driven feed-roll, and A the idle feed-roll, of a type-writing machine.

These rolls are both rotatably supported on parallel axes upon the framework C of the machine. I When the machine is being used in the ordinary way, the feed-roll A and a concentric ratchet-wheel B are frictionally connected together, and the turning of the feed-roll 1s to be effected by the usual or any appropriate mechanism acting upon the ratchet-wheel.

The feed-roll A is secured upon a concentricv metallic tube D, which passes entirely throu h it and extends a considerable distance eyond the roll at one end thereof. At its other end this tube is preferably flush with the end of the roll. The projecting end (I of I gpecification of Application filed July 13, 1906. Serial No. 326,072.

Letters Patent. Patented Jan. 29, 1907.

the tube is provided with a convenient knob d, by which the feed-roll may be turned backward or forward when disconnected from theratchet-wheel. Moreover, this projecting end (Z is rotatably mounted in a fixed member 0 of the machineframe, and thereby the corresponding end of the roll is rotatably supported.

A cylindrical rod E asses entirely through and is rotatably fitted to the tube D: The ratchet wheel Bisrigidly secured to this rod adjacent to the end of the feed-roll A. Beyond this ratchet-wheel this cylindrical rod E is rotatably mounted in one of the fixed frame members '0. By so mounting the projecting end of rod E the correspondin end of the feed-roll is rotatably supporte The opposite end of the rod E is provided with means by which it may be drawn through 'tube D, with the result of clutching the roll and ratchet-wheel together. In the construction shown the projecting end of rod E is threaded. The nut 6 screws onto "the same and bears against the end of tube D. A friction-washer G is preferably interposed between the ratchet-wheel and the adjacent end of the feed-roll. By turning up the nut the rod E is drawn through the feed-roll and the ratchet-wheel brought into frictional en gagement with the end of the rollkoz rather, in the specific construction shown with the friction-washer .G, which is thereby ushed against the end of the feed-roll. The roll and the ratchet-wheel are thus clutched together through the frictional engagement of rollbackward or forward to bring any part of the paper into the impression-line the operator loosens the nut e. As the result of this the operator may by taking hold of the knob loose upon the shaft, and the thumb-nut e, A

which screws onto the end of shaft E, bears against the hub of the ratchet B and moves itupon shaft E intofrictional engagement with collar a. By looseningthe nut e the shaft E, together with the feed-roll attached thereto, may be turned independently of the ratchet-wheel, the wheel a being proyided for that purpose.

Having described my invention, I claim- 1. In a t e-writing machine,-the combination of t e rotatable feed-roll, a tube which extends axially through said roll and beyond one end thereof, which tube is fixed to said roll, a cylindrical rod passing through said tube, a ratchet-wheel fixed to said rod adjacent to one end of the feed-roll, and mechanism for drawing the rod endwise through the tube to frictionally clutch said ratchet and feed=roll together.

2. In a type-writing machine, the combination of the rotatable feed-roll, a tube which extends axially through said roll and beyond one end thereof, which tube is fixed to said roll, a cylindrical rod passing through said tube, a ratchet-wheel fixed to said rod adjacent to one end of the feed-roll, and a clamping device screwed to the rod but engagingwith the adjacent end of said .tube,

3. In a type-writing machine, the-combis nation of the rotatable feed-roll, a tube which extends axially through said roll and is fixed thereto and extends beyond oneend of said roll, said projecting end being rotatably mounted in the machine-frame, a cylindrical rodwhich extends through said tube and beyond the feed-roll, said projecting end being rotatably mounted in the nxachine-lrame,, a rotatable wheel fixed to the projecting end of said rod adjacent to the feed-roll, and a device screwed to the other end of said rod in engagement with the adjacent end of said tu e.

In testimony whereof I hereunto aifix my signature in the presenceof two witnesses.

JOHN MAYNARD.
